Yahya related to me from Malik from Hisham ibn Urwa that he saw his father wiping over his leather socks. He said, "When he wiped over his socks he would never do more than wipe the tops and he would not wipe the bottoms."  

قَالَ وَكَانَ لاَ يَزِيدُ إِذَا مَسَحَ عَلَى الْخُفَّيْنِ عَلَى أَنْ يَمْسَحَ ظُهُورَهُمَا وَلاَ يَمْسَحُ بُطُونَهُمَا  

Yahya related to me that Malik had asked Ibn Shihab how to wipe over leather socks. Ibn Shihab had put one hand under the sock and his other hand above the sock and then passed them over it. Yahya said that Malik said, "Out of all that I have heard about the matter I like what Ibn Shihab said the most."  

عَنِ الْمَسْحِ عَلَى الْخُفَّيْنِ كَيْفَ هُوَ فَأَدْخَلَ ابْنُ شِهَابٍ إِحْدَى يَدَيْهِ تَحْتَ الْخُفِّ وَالأُخْرَى فَوْقَهُ ثُمَّ أَمَرَّهُمَا قَالَ يَحْيَى قَالَ مَالِكٌ وَقَوْلُ ابْنِ شِهَابٍ أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي ذَلِكَ
